Abstract (en)

This invention provides methods useful in aiding in the diagnosis of Alzheimer's disease. The methods involve measuring the amount of amyloid- beta peptide (x-≥41) in the cerebrospinal fluid of a patient. High levels of the peptide generally are inconsistent with a diagnosis of Alzheimer's. Low levels of the peptide are consistent with the disease and, with other tests, can provide a positive diagnosis. Other methods involve measuring the amounts of both A beta (x-≥41) and tau. Low levels of A beta (x-≥41) and high levels of tau are a positive indicator of Alzheimer's disease, while high levels of A beta (x-≥41) and low levels of tau are a negative indication of Alzheimer's disease. <IMAGE>

Diagnosis and monitoring of Alzheimer's disease (AD) is aided by: (a) measuring the amount of at least one soluble Abeta (x->= 41) peptide (I) in a test sample; (b) comparing the result with a predetermined amount of the same peptide; and (c) assessing patient status from the difference.
